Damn that's very good! I don't have enough brains to understand puzzles, even with hints (?), but even without them it's just a neat unfiction story.
Visuals definetely carry, especially formating of all menus and pages. And it works best when your control is taken away. Sound design only enchanses the whole thing.
I will try to figure out puzzles when I'll be in a bit brighter state of mind, but I'm already satisfied with what's told and implied on the surface.
